Bristol aims to become UK’s first ‘wetland city’ and reduce flood risk

By · Via The Guardian Environment · Published by Everything Blog

In short

The Wildfowl & Wetlands Trust and Bristol City Council are rolling out nature-based solutions ranging from household rain gardens to large-scale floodplain reconnections. Work launched in September with the deployment of plant-covered floating wetlands across three spots in the city-centre harbour. By capturing and filtering precipitation where it falls, these living systems prevent traditional sewer networks from overflowing during severe storms. The ultimate goal is earning recognition under the global Ramsar treaty, which currently honors dozens of wetland municipalities worldwide.

Bristol could become home to the UK’s first “wetland city” thanks to a charity’s efforts to create vast wildlife corridors that will reduce flood risk and give people more access to green and blue spaces.

The Wildfowl & Wetlands Trust (WWT) said the five-year initiative would include more than 200 projects to restore and create wetlands across the city. These will range from small household rainwater ponds and street-level rain gardens to restoring river habitats, reconnecting rivers with their floodplains, and creating new wetlands.

It hopes to achieve wetland city accreditation under the Ramsar convention, the international treaty on wetland conservation, which recognises cities that protect and make wise use of their urban wetlands.

The charity kickstarted the project in September by installing floating wetlands, made of buoyant modules covered in wetland plants, at three sites in Bristol’s city-centre harbour. They help to create a more welcoming habitat for insects, birds and other wildlife.

“Within minutes, dragonflies and other wildlife were appearing. Nature was being drawn to it,” said Peter Lee, the programmes lead at WWT. “It sparked a conversation…
